Maya Crashes When Rendering with Arnold

[Anonymous]

Hello,

I am new to Maya and taught myself the program through the help of good ol' Youtube. I recently got a PC with an RTX3070 GPU and did all the settings to have Arnold render with my GPU in Maya 2020. I tried a blank new file and made a simple circle and it seemed to have rendered fine, but for the specific scene, I need to render my file simply crashes when I hit render. It doesn't even give me a chance to select Denoise.I optimized the file and got rid of any error nodes, and searched all the forums back and forth about what could possibly be causing this issue. I'm hoping someone can take a look at the file itself and try rendering it on their end and see if it has to do with the textures themselves. Some textures are lamberts and some are Arnold textures. In my CPU the process is quick but the rendering isn't the cleanest. I eventually plan on animating in this scene so it is crucial that I can get my GPU to work with this.

All those warnings are for stuff not supported yet on the GPU.

MayaFractal, MayaLeather, and the contourn filter are not supported on the GPU.

You can use aiBump shaders, those are supported.

Hello Stephen! 

Thanks for responding to my question. I never used an aiBump so I don't exactly know what that means. All my textures that I have created are either lambert's or AiStandard Surfaces, some of these have bump map geometry in it. Is it referring that instead of adding a bump map to the AiStandard Surface I add it to an AiBump? I hope this makes sense. It doesn't help that I'm not very knowledgeable of the program and everything Arnold has to offer.
